Python PIL sometimes can't convert ico to png

Question

I need to convert the favicon with ICO format to PNG. I tried to do it with the PIL:

img = Image.open('favicon.ico')
img.save('favicon.png', 'png')

But often the conversion was incorrect, since after it favicon not displayed. I was looking for other ways to convert, for example, the PIL has IcoImagePlugin, but I knew he was not to convert. What more way can perform a task?

Note the comment in the duplicate. If the ICO contains multiple images, conversion to PNG will appear to fail because PNG is a single-image format. — Glenn Randers-Pehrson, Aug 13 '15 at 16:07
i took the advice in dublicate about choosing the size of ico, but it also did'nt help. — Юля Быкова, Aug 14 '15 at 07:41
You can only save to PNG if the original ICO contains a single image, or if you extract a single image from the ICO. Otherwise you'll get favicon.png.0, favicon.png.1, etc. — Glenn Randers-Pehrson, Aug 14 '15 at 11:44

Works for me. But PIL is quite old and does not work on python3 so on python3 i'm using the friendly fork: Pillow. By the way: it also accepts

img.save('favicon.png')

Are you sure there is nothing wrong with you favicon ?

Favicons I take from sites, but in ico they are viewed. I also use the Pillow – Юля Быкова Aug 13 '15 at 11:01
